My current goal is 20 units in 5 years. 

Interest Rate: I'm trying to use conventional loan with 5% down (30 years term) as my goal to purchase my first property.

I am not sure of my timeline but I'm gonna set a goal of positive cash flow within the next 12 months. 

Im looking into other markets since I am going to eventially need to start buying several houses per year if I'm going to meet my goal of six figure passive income by 2027.What do you do when you are out of money to invest or have no other deals to pursue?

If you really know your investing criteria and those criteria support your goals, stick to them.

I have big goals of buying lots of real estate in the next 10 years. any advice would be greatly appreciated!

Depending on what your long term goals are, you might be better off investing in a mutual fund.

Will the property reach your ROI and cashflow goals if you have to spend more money than you planned after closing?

Not only will this put more money in your pocket, but depending on your goals, you can paydown the debt far faster with this method.

To put it simply, I have two goals on a BRRRR.
